The vertical mixer cannot be rotated in winter
Thread Content
There is a vertical mixer that was left idle for several months during the winter, and now it won’t rotate – what could be the reasons for this?
Conditionally disconnect the coupling first to determine whether it is a problem with the motor or the fact that the mixer cannot rotate. If the mixer cannot rotate, it is most likely a bearing issue
Agree with the opinion above. First, disconnect the coupling, and then inspect both the motor and the mixer simultaneously. If there is a reducer, its rotation should also be checked. Most reducers are cycloidal pinwheel reducers, and the eccentric bearings and cycloidal rollers inside them need to be inspected regularly and lubricated. Next, check the bearings of both the motor and the mixer. Finally, verify whether there is any jamming or rust in the submerged part of the mixer shaft
